SPECIFICATION forming To all whom it may concern:

Be it known that we, JOSEPH E. CRISP, of Boston, in the county of Suffolk, and GEORGE 1V. GOPELAND, of Malden, in the county ot Middlesex, both in the State of Massachusetts, citizens of the United States, have made a certain Improvement in Boot Treeing Machines, ot' which the following is a full, clear, and exact description, reference being had to the accompanying drawings,forming a part ot' this specilieation in explaining its nature, in which- Figure 1 represents a view of our improved machine, part in side elevation and part in section. Fig. 2 is a view, part in plan and partin cross-section, of the portion below the dotted line c c of Fig. 1. Fig. 3 is a plan of a portion of the top of the machine. Fig. a is an enlarged view, in elevation, of a part of the operative mechanism. Fig. 5 is a sectional view of a portion ofthe mechanism shown in Fig. 4. on the line a; mofFig. 3. Fig. (i is a plan and section of the part ot the machine below the dotted line 1/ y of Fig. 1. Fig. 7 is a section on the line to wot Fig. 3. Fig. 8 is a plan of a sector employed in transmitting movement from one part of the machine to another. Fig. J is a perspective of a portion of the tool or rub-stick employed on the side and bach surfaces ofthe boot. Fig. 10 is an end elevation thereof, the boot and boot-tree being shown in cross-section. Fig. 11 is 'an enlarged view ot' a part of the tool shown in Fig. 9, and Fig. 12 is a side view of one portion ofthe tool to illustrate the mechanism for obtaining a movement hereinafter described.

This invention embraces, tirst, means for providing' a boot-tree with partial rotation upon its axis, forward and back, whereby sections of the boot are presented and withdrawn from the tool or rub-stick without entirely revolving the tree; second, means for providing the boot-tree with complete rotation upon its axis, adapted to be alternately used with the mechanism for providing it with partial rotation, third, means' whereby the same operative mechanism is employed for giving two or more boot-trees these movements; fourth, a rnbstick of peculiar construction adapted to part of Letters Patent No. 232,944, dated October 5, 1880. Application tiled August 1G, 1880. (Model.)

operate upon the side and hack portions ofthe boot; fifth, means for providing Said rub-stick with a reciprocating movement between the heel and knee end of the boot-tree; sixth, the combination of a rubstick adapted to be reciprocated upon the boot-leg with a. boot-tree having a movement of rotation torward and back upon its axis, seventh, the combination of a boot-tree having a movement of rotation either continuons in one direction or forward and back with a rub-Stick adapted to be reciprocated automatically upon the side and back portions ofthe boot-tree, and with a rnb. stick adapted to be reciprocated upon the front, sides, and foot portion of the tree by hand; eighth, various details in construction and organization, all of which are hereinafter more fully described and the chief Object of the invention is to provide means whereby the larger and easier portions ofthe boot to finish are treed automatically, while the smaller and more difficult parts are hand-finished; and in order that the automatic tool may do as much work as possible, and yet not interfere with the operation of the hand-tool, we have oscillated the surface ofthe tree in relation to said automatic tool, thereby presen ting sections of the boot to the tool that otherwise could not be reached by it unless the working-surface ofthe tool were lengthened, in which case it would interfere with the free use ofthe handtool, and would therefore have to he done by hand.

In the drawings, A represents the boottrees. They are supported at their knee end substantially as described in reissue Letters Patent granted to Joseph E. Crisp, assigner, Nos. 9,055 and 9,124, and the trees are made expansible and are heated, if desired. They are also adapted to be revolved, in presenting them in succession to the rub-sticks, with the jack B, from which the hollow posts or sleeves which support the trees radiate horizontally, and which, with the posts, is similar in construction and operation to the jack shown and described in said Letters Patent No. 9,124.

Each post or boot-tree is provided with a disk, ci., which has the grooves c c2 in its circumference, when it is desired that the boottree should be provided w'ith a movement of rotation forward and back and with a continuous revolution in one direction.

The'mechanism for communicating a movement of rotation forward and back to the tree consists of the main shaft a3 ot' the machine, the revolving arm a4, which furnishes a bearing for the gear-wheel a5, and which revolves it around the shaft; the fixed gear-wheel a6, that is fastened to a sleeve, a7, projecting upwardly from the post t8 the gear-wheel a9, which is fastened to the sleeve projecting upwardly from an eccentric, alo,- the said eccentric, the eccentric-bar au, which connects the eccentric with the bevel-gear al2 and provides it with a partial movement of rotation back and forth, the double sector als, which has teeth am upon its upper face to engage with the bevel-gear c1112, and a frictioi'l-surface, 015, V- shaped in cross-section upon its lower surface to engage with the groove a in the disk a.

The sector and the bevel-gear cl2 have suitable bearings in the bracket al projecting outwardly from the post.

The gear attached to the eccentric has one less tooth than the fixed gear above it, and upon the revolution ot' the gear-wheel a5 around them the gear attached to the eccentric is moved very slowly, consequently this provides the eccentric with a very slow rotation. This movement can be increased by decreasing the number ot' teeth. A clutch, or one member thereof, al, sliding on a tast ieather on the shaft, and provided with a vertical movement thereon, as hereinafter' explained, is adapted to engage with the other member on the swinging arm a4 in providing it with revolution.

Although the part a ot' the clutch may be engaged or disengaged by any suitable mechanism, we prefer to operate it by the arm C that supports the upper rub-stick. rIhis arm, preferably, is curved, as represented in Fig. 3. It is secured to the bracket c by the stud or pinion c, and it has formed on the upper portion surrounding the stud a screw-thread, c2, which receives the screw-thread 03 upon the arm c4, which carries the portion a ot' the clutch. Upon a slight lateral movement of the arm G on the center c the screw is revolved, causing the arml c4 and the part a of the clutch to be lifted upwardly, thereby disengaging that portion of the clutch from its other part.

When means are provided for continuously revolving the boot-tree in one direction it is desirable that the mechanism for partially revolving it, as above described, shall be lifted sufficiently to disen gage the portion 015 of the sector from the groove a', and to eect this, although other mechanism may be employed, we again prefer to use the arm C.

Y vIn order that this portion of our invention may be understood it is necessary to state that the brackets am and c are attached to or formed on a collar or sleeve, d, and that provision s supplied for moving the collar and the mechanism that it supports and the mechanism on the shaft above it vertically upon the post a8 and shaft. and this we accomplish by means of the wedge or inclined block D, the slot d in the collar d having its upper wall shaped to conform to the inclination ot' the wedge or inclined block. The block is given a horizontal movement by means of the lever cl2, pivoted at d3 to a bracket extending outwardly from the sleeve d and the link d4, that connects one end of the lever with the arm C. Upon `the movement of the arm away from the boot-tree the lever is opera-ted to move the block D inwardly,

.thereby causing the collar to litt upon its inclined surface, and it maybe closed 11er-.moved inwardly sufiicient to allow its inner end to rest upon the notch d5 in thc post a8.'

The arm C is provided at its outer end with a yoke, c5, that supports the cylinder c, the cylinder being provided with trunnions or projections which are supported by the ends of the yoke, and which enable the cylinder to be rocked or oscillated in a direction lengthwise of the boot-tree.

rEhe mechanism for providing` the boot-tree with continuous revolution consists in the gearwheel c, near the lower end of the main shaft a3, the gear-wheel c', having suitable bearing in the frame A', and the gear-wheel c2, which has a circular V-shaped projection, c3, on its upper face, and a long sleeve, e4, projecting downwardly into its bearing e5. The V-shaped projection c?, when the gear-wheel is moved upwardly by the rod e6, lever el, pivoted at e8, and treadle c, pivoted at 010, engages with the V-shaped recess or groove a2 in the disk a.

We do not, however, intend to confine ourselves to the use of the two sets of' mechanism herein described for providing the boot-tree with partial or continuous revolution, but may use either separately. Neither do we intend to confine ourselves to the special forms of seetor, nor to the method ot operating the revolving disk a by the t'rictional contact of the sector or projection e3 therewith, nor to its form, but may use in lieu thereofl a gear-wheel in the one instance and a bevel-gear in the other. Neither do we confine ourselves to the specific mechanism described for providing the tree with its movement of partial revolution to and fro, but we may use any known appliances for providingthe same with said movement without departing from the spirit of this invention.

The rub-stick supported by the cylinder cG is described in our application for patent for improvement in boot-treeing machines filed July 2, 1880, and it is unnecessary to give a further description thereof here, with this eX- ception: The rub-stick is held against the boot-tree by com pressed air. I t is so supported as to have universal movement in relation to the surface ot' the boot-tree, and it is adapted to be reciprocated upon the front part of the boot-tree and upon the foot portion by hand.

IZO

The rub-stick for operating upon the sides and back portion of the boot-tree is supported upon a pistonrod,f, and the cylinder f', and the rub-stick is pressed against the surface of the boot-tree by compressed air or other like elastic pressure.

The cylinder is suitably supported by a block,f2, which is reciprocated on the ways f4 in the bracket or table f5 by the crank f6 on the lower end ofthe shaft c3, and the connecting-rod f7, and the sleeve f8. The connecting-rod f7 and sleeve f8 are used for the purpose of providing an adjustment of the block f2 to and from the main shaft, and in order that the rub-stick may be set to the length of the-.boet-tree, and this is accomplished by moving Jthe sleeve inwardly or outwardly from the rod f7, as the case may he, and then locking then by a locking-screw.

rlhe lower rub-stick, G, preferably consists of two parts, g g', adapted to bear upon opposite surfaces of the boot-tree or surfaces very nearly opposite, and we prefer to use three lines, g2g/3 g4, of pads, four in a line. The pads in the line g4 are pivoted in relation to each other and to the rod g5 substantiallyv as the pads, in our application of July 2, 1880, are pivoted to their supporting bar, and have therefore the pivots or centers g5, g, and g7 for providing Jthe pads with the conformability necessary. The lines g2 g3 have centers correspending to the centers g5 g'3 gT for the same purpose, and they are also provided with another center, g8, caused by the manner of supporting the blocks gf), which hold the rods gw, that connect the arm g for carrying the pivots for the pads. These blocks gf are pivoted to the arm 012 in such a way that upon the movement of the two lines of pads g2 gil toward the knee end ofthe boot both lines bear with equal force, or substantially equal force, upon the boot-tree or boot-leg thereon; but upon the backward movement, or movement from the knee end of the tree toward the heel, the line g2 of pads is lifted from the boot-tree or boot thereon automatically, and sufficient play for this movement of the block g" is provided, as represented at p13, Fig. l2, but not sufficient to prevent the line of pads g3 from bearing on said hacluvard or reversed movement. This construction of rub-stick is desirable in order that the upper border or edge of the boot may be thoroughly treed and linished, and in order that provision may be made for differences in the length of boot-legs, and in operation the line g2 of pads is moved beyond the upper or knee end of the boot upon the boot-tree on every reciprocation of the stick, and on every reverse or backward movement the line is lifted to cl= ar the edge, thus preventing its racking and the catching of the pads upon it.

It is obvious from this description that all boots varying in height the distance between the two lines g2 g3 of pads may be treed without changing the rub-stick.

The arms 912 and y, which support the lines `front and foot portions of the boot.

of pads, are connected by the rod gw, which is pivoted at gm to the arm g, and the two arms g17 are fastened to the piston-rodj'.

The pipes and valves for conveying the compressed air to the cylinders c6 andf and for controlling its use are not herein shown, as they are of ordinary construction and are used in the ordinary way.

We propose to utilize the base H of the machine as a reservoir for compressed air, and from thence to conduct it to the cylinders.

The piston-rod f is of sufficient length to provide the under rub-stick with a considerable vertical movement in relation to the tree, in order that it may be out of the way when not in use sufliciently to allow the operator to wire the tree or otherwise manipulate it.

We do not eonline ourselves to the special method of reciprocating the block f2, nor to the special form of the lower rub-stick herein described, but may use in lieu of the pads described one or more of the rolls, pads, or rubsticks described in the various patents relating to the art of boot-treeing.

The operation of the machine is as follows; The boot is adjusted upon a boot-tree and the necessary composition applied, and the tree is then presented to the action of the rubstick. The lower rub-stick is moved upwardly automatically by the compressed air in the cylinder upon opening a valve, and automatically conforms tothe surface of the boot-tree. lt is then reciprocated, while the boot-tree has a partial movement of rotation upon its axis forward and backward. This brings all portions of the sides and bottom of the tree in position to he operated upon by the rub-stick duringsomeportionofitsreciprocation. While the under rub-stick is thus automatically tinishing the sides and back of the boot the upper rub-stick is being moved by hand upon the While this work is being done by one operator another is preparing the second boot upon another tree by adjusting it thereon and applying the composition. Upon the completion ofthe rubbing of the first tree by the movement of the arm C to the right and by the opening of a valve, the upper rub-stick is removed from the work and the lower rub-stick lowered therefrom sufliciently to expose the tree to the action of strapping and such other manipulation and to such inspection as may be necessary. Upon the further movement ot' the arm C to the right the mechanism for giving the boot-tree a partial movement of rotation is disengaged, and the mechanism for revolving it continuously in one direction can then be used. This last-named provision is of some advantage in revolving the boot-tree, in order that the operator may inspect his work thoroughly before removing` the hoot from the tree.

Of course, in lieu of giving the boot-tree a partial movement ot' rotation back and forward, the under rub-stick can be provided with such traversing movement back and forth as shall IZO 4 acarrea correspond and be equivalent for the partial revolution of the tree, and shall accomplish the same purpose; and in lieu of the upper rub-stick, held as described, any ordinary handtool operated-by hand may be used.

Having thus fully described our invention, we claim and desire to secure by Letters Patent of the United States- 1.
